In 1979, Oh Dawn! Inc. released "The Amazing Spider-Man & the Incredible Hulk" in "The Gamma Gambit," a short comic printed entirely on toilet tissue.

Frankly, I think the Incredible Hulk is a terrible choice for this comic, as he's likely the only mainstream superhero who's not toilet-trained. The comic was penned by Jim Salicrup and Michael Higgins and illustrated by Marie Severin. Read the whole bizarre script here.

There are approximately 10,000 scatological jokes I could make about this product, but my mind is overwhelmed by the sheer amount of juvenile wordplay and puerile puns. Here's a video of this magical T.P. for all you skeptics out there in internet-land.
